SPECIFICATION forming part of Letters Patent No. 790,792, dated May 23,1905.

Application filed September 9, 1904. Serial No. 223,868.

To LZ' wwm/ it may concern:

Be it known that I, JOHN S. KIDDEY, aciti- Zen of the United States,residing at Canton, in the countyof Stark and State of Ohio, haveinvented certain new and useful Improvements in Steam-Generators; and Ido hereby declare that the following is a full, clear, and exactdescription of the same, reference being had to the annexed drawings,making a part of this specification, and to the numerals of referencemarked thereon, in which# Figure l is a vertical section of the furnaceLwall, showing the proper arrangementof the drums or boilers and theirproper connection. Fig. 2 is a horizontal section on line 2 2, Fig. l.Fig. 8 isa detached view of thelowerlefthand drum or boiler, shown inFig. l, except that the vertical series of water-pipes are not shown inreference to said drum or boiler.

Similar numerals of reference indicate corresponding parts in all thefigures of the drawings.

In the accompanying drawings, l represents the furnace-wall proper,which is formed of brick or other suitable material and of a size toreceive the various drums or boilers and to permit them to be arrangedin substantial accordance with the arrangement illustrated in Fig. l,and as shown in Fig. l the drums or boilers 2, 3, 4, and 5 are arrangedabout equal distances apart and the drums or boilers 4 and 5 locatedsubstantially in a vertical line above the drums or boilers 2 and 3. Thedrum or boiler 6 is located in a plane above the tops of the drums orboilers 4 and 5, which boiler receives the steam generated in the drumsor boilers below said upper boiler and. also the steam generated in thevarious pipes hereinafter described.

The front wall of the casing-wall is provided with the usual fire-door7, and it will be understood that any desired number of doors may beemployed, owing to the fact that the drums or boilers extend crosswiseof the boiler casing or walls instead of lengthwise.

The bottom or lower portion of the combustion-chamber is provided withthe ordinary grates 8 and the lower forward boiler or drum 2 locatedabove the combustionchamber.

At the rear of the combustion-chamber proper is located the back wall 9,which back wall is inclined upward and rearward, so as to guide or shuntthe flame, heat, and smoke upward between the boilers 2 and 3, {irstpassing the water-tubes l0, said water-tubes being connected to theboilers 2 and 3 in such a manner that water connection is maintainedbetween the boilers 2 and 3. After the heat and iiame have passed thewater-tubes 10 their source will be upward under the pipes 11 and thebaffle-wall 12, passing the water-pipes 13, which water-pipes connectthe boiler 3 and the boiler 4. Vithin one ot' the pipes l0 and one ofthe pipes 13 is located an air-pipe, which air-pipe is extended throughtheboiler 3 and is for the purpose hereinafter described. The heatedair, together with the flame and smoke, will ascend upward and incontact with the boiler 4 and the curved top 14 of the furnace-wall, andby reason ot' the draft of the chimney or tlue 15 the heated air andiiame and smoke will be shunted downward, passing the pipes 16, 17, and18, the pipes 16 and 17 all communicating with the upper boiler 6 andthe pipes 18 communicating with the boilers 4 and 5. As the heated airand flame are carried to the ilue or chimney they will pass the pipes19, it being understood that the downward passage is upon the oppositeside of the balie-wall 12 from the upward passage, or, in other words,the upward passage is under the battle-wall and the downward passageabove said baiiiewall, which baffle-wall is held in place by the pipes ll or their eq uivalents. It will be understood that the wall is of lightconstruction, as the only object is to cut olf the direct draft Jfromthe combustionchamber to the flue or to produce a divided upward anddownward draft.

By locating the various boilers or drums 2, 3, 4, 5, and 6 asillustrated and connecting them by means of the various pipes they areall connected together and in such a manner that the steam generated inthe various boilers and tubes will find its way to the upper boiler 6,which boiler is located where it will receive the heat arising from thecombustioncharnber, and by providing the up and down draft all of theboilers and all of the tubes will present radiating-surfaces.

For the purpose of producing what might be termed a more rigidconnection between the various boilers some ot' the connectingpipesarecurved, and for the purpose of producing a strong connection betweenthe various boilers the water-pipes should be, and preferably are,staggered, as illustrated in Fig. 8.

The boilers or drums 2, 3, 4:, and 5 are held in fixed relative positionwith reference to the furnace-wall by setting the ends of the variousboilers in the end walls of the furnacewall 1, so that each drum orboiler is provided with independent supports.

From the boiler 2 extends the inclined wall 20, which inclined wallforms the top of the combustion-chamber at its forward portion.

The fu rnace-wall is provided with the cleanout opening 2l, whichclean-out opening is provided with the door or doors 22. The object andpurpose of this arrangement is to provide a means for removing from timeto time the soot or ashes that may accumulate upon the top of theinclined wall 20. The rear side of the furnace-wall is also providedwith the opening 23, which opening leads into the pit 24, it beingunderstood that the opening 23 is to be provided with adoor or doors.

The feed-pipe 25 may be connected to the boiler 5 or it may be connectedto any of the different boilers;l but in 'any event it will beunderstood that a single feed-pipe is designed to supply water to all ofthe various drums or boilers and their connecting-pipes.

For the purpose of providing means for cleaning the interior of thefurnace-walls end doors 27 may be provided and are so located thataccess may be had to the interior of the structure.

For the purpose of preventing the water from backing up the pipe 26 isprovided, which pipe is located in one of the connecting-pipes l0 and13, said air-pipe being extended above the level of the upper'horizontal pipe l0 or the curved pipe of the series, by whicharrangement the accumulation of air will be carried above the level ofthe boilers 2 and Stduring the time the said boilers or drums are beingfilled; -but after the full supply of water has been fed to thegenerator proper the air-pipe in a sense becomes an idle element, andits use is especially to prevent the backing or' water during the timethe generator is being refilled.

For the purpose of providing a means for cleaning the boilers orremoving the water therefrom the ordinary blow-out pipes 28 are providedand are located in the usual manner.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent. is-

1. In a steam-generator, a series of drums located laterally adjacent,said series consisting of two pairs of drums, one pair located above theother, and the remaining drum of the series located above the Lipperpair of drums, pipes communicating with all the drums of the series, abafHe-wall extended upward from one of the lower pairs of drums to oneof the upper pairs, said baiile-wall extended in an inclined directionbetween the upper and lower pairs ofdrums, a combustion-charnber locatedbelow the baiiie-wall and a chamber located above the baffle-wall andone of the series of drums located entirely below the baffle-wall andtwo of the series of drums entirely above the baflie-wall, and theremaining drums of the series located coplaner with the baiie-wall, anda Hue leading from the chamber located above the baffle-wall,substantially as and for the purpose specified.

2. In a steam-generator ot' the class described, the combination of-aseries of drums located laterally adjacent, and in dierent horizontalplanes, four of the series being located in two different horizontalplanes and one of the series in a horizontal plane above the remainingdrum of the series, pipes communieating with all of the series of drums,abaiilewall located in an inclined plane dividing two of the series ofdrums-coplaner, and one of the remaining series located below thebalewall and the two remaining drums of the series located entirelyabove the baiiie-wall, a combustion-chamber located below thebafflewall, a flue-chamber located above the baffle-- wall, an inclinedwall dividing the combustion-chamber and flue-chamber, and a rear pitlocated at the rear of the furnace, substantially as and for the purposespecied.

3. In asteam-generator, the combination of a series of drums, pipescommunicating with all the drums of the series, a combustionchamber anda due-chamber, a battle-wall located between the combustion-chamber andthe luechamber, and an airpipe located within pipes, said air-pipeextended through one of the drums of the series, substantially as andfor the purpose speciiied.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.
